Description; Chapters; Supplementary; This book presents the latest achievements of separation science and technology. It highlights the application of separation with regard to problems of current interest, such as the protection of the environment and the development of emerging technology, including chemical engineering, biotechnology, renewable energy sources and recycling of materials.
Pyrite is a very hard mineral of a pale brass color, found in scattered crystals in many rocks, and is composed of iron and sulphur (iron sulphide). Under the attack of the weather it takes up oxygen, forming iron sulphate (green vitriol), a soluble compound, and insoluble hydrated iron oxide, which as a mineral is known as limonite.

Welcome to the 2017 Sustainable Industrial Processing Summit and Exhibition. Following the previous rich tradition, the summit will cover 3 sustainability pillars (1) Science, Technology and Industrial Practice, (2) Political and Social Framework and (3) Education.
An apparatus for forming liquid hydrocarbons from solid coal. The coal is pulverized to provide a particulate coal feed, which is then extruded to provide a hollow tube of compressed coal supported inside of a support tube. A clay feed is extruded to provide a hollow tube of compressed clay supported inside of the coal tube and a combustible fuel is burned inside of the clay tube.
The gold can be fairly easily removed from the amalgam by distilling off the mercury. In internal amalgamation, the gold is separated inside the crushing apparatus at the same time as the ore is crushed. The amalgam removed from the apparatus is washed free
Extraction data obtained from flotation experiments indicated that the role of humic acids naturally present in the ores was basically that of a depressant of bitumen since poor ores contained the highest proportion of humic acids per gram of bitumen. A role of humic matter and ore oxidation in rheology of oil sand slurries and in bitumen

However, to improve the quality of materials, it is necessary to increase the foam stability. For this purpose it is proposed to use a mineral modifier of silicate composition (NM) based on quartz sand, obtained by wet stage milling of raw materials in a ball mill.
